The evaluation methodology on carbon emissions of passenger cars based on travel characteristics

Abstract

In recent years, with the rapid growth of economy, China’s urbanization and urban transport are undergoing a rapid development, resulting in a large amount of travels. But at the same time, due to “blowout” growth of passenger cars, a series of serious social problems occurred, such as traffic congestion and fast increase in Carbon Dioxide emissions, which posed a great challenge to the sustainable development of urban transport in China. Studies on the evaluation methodology of Carbon Dioxide emissions based on travel characteristics are to be conducted to effectively improve the evaluation accuracy of emission quantification of passenger cars, and find out the place and source of Carbon Dioxide emissions, so as to further promote accurate emission reduction. This paper first analyzes the main characteristics of Carbon Dioxide emissions of passenger cars in China, optimizes the evaluation methodology of Carbon Dioxide emissions of passenger cars from the perspectives of scoping, road grading and classification evaluation, and conducts a test on Carbon Dioxide emission factors in some cities. The paper also takes Harbin city as an example to evaluate its Carbon Dioxide emissions of passenger cars from 2014 to 2016, so as to testify the feasibility of the methodology.
